I upgraded the firmware of my XCube II earlier today. Before, it shows v 1.06. Now, it reads v 1.098. And I have to say, it functions pretty well now. The ramp up time is much faster compared to before. And they added a Min and Max mode, when before it was just Soft, Normal, and Hard. Also noticed that the fire time starts the second you click the fire button. I’m so glad I finally took the time to upgrade this mod.
I notice in online forums that there are a lot of people who experience issues when upgrading. I did it once, and everything went well.
